Description
Technical field
The present invention relates to fixing wireless area network (WRAN) technical field, more particularly, the present invention relates to inter-cell communication method and the system of a kind of WRAN.
Background technology
In October, 2004, Institute of Electrical and Electric Engineers (IEEE) is formally set up IEEE802.22 working group, IEEE802.22 another name for fixing wireless area network (Wireless Regional AreaNetwork, WRAN).The purpose of this working group is to use cognitive radio technology, and the idle frequency band of seeking permitted user (LU) communicates.Such as, in the licensed band such as VHF/UHF of wireless digital TV-set (DTV), seeking does not have the carrying frequency range of occupied frequency range as the WRAN network.
The WRAN network is a kind of emerging network technology, can for remote districts, provide high bandwidth to cover on a large scale than low-density population area.The WRAN system is a kind of system that exempts from permission operation (license-exempt operation), simultaneously, also all exempt between the WRAN system to permit, can be used by a plurality of operators, therefore the WRAN system does not have frequency spectrum planning, may have self-interference between the base station of WRAN (BS).
The physical technique of current WRAN system uses the OFDMA technology based on TDD to communicate.Each frame structure of WRAN system is divided into two subframes, is respectively a descending sub frame and a sub-frame of uplink, the centre guard time (can insert TRG or SSS slides from coexisting time slot) of being separated by.Descending sub frame comprises a Preamble, and client device (CPE) can carry out synchronously and the signal estimation with Preamble; Be frame control head FCH then, be used for carrying the information of present frame, such as whether comprising US-MAP message, DS-MAP message, UCD message, DCD message etc. in the present frame; Wherein US-MAP and DS-MAP are used for respectively to each CPE allocation of downlink and up channel.
Say that broadly coexistence refers in the neutralize coexistence of other overlay cells of identical wireless system certainly, this is a key issue of the wireless communication technology of operating in non-licensed band.When a plurality of BS when 802.22 worked an overlapping region, this problem was especially outstanding.And the base station may belong to different operators, can not cooperate and frequency planning.Because these characteristics, 802.22 face the baptism that how to solve from coexistence problems.In other IEEE 802 standards, from coexistence all is just to consider after norm-setting is finished, and IEEE 802.22 adopts prospective method (as statement in the requirement documents of standard), MAC forced must comprising Zi coexist agreement and algorithm to originally standard concept and definition.In IEEE 802.22 standards, different mechanism, (On-Demand Spectrum Connection, ODSC) algorithm and the lease agreement that characterizes based on credit are with solving from coexistence problems such as need-based frequency spectrum competition.In these mechanism, the information that coexists certainly exchanges between the base station.These information are for extremely important from coexistence mechanism, thereby they are very high to the demand of reliable transmission.
In order to reduce the self-interference phenomenon of WRAN, need the frame of neighbor cell be alignd, make that the downlink frame between the sub-district can be synchronous, thereby the signal that reduces the different directions between the sub-district disturbs.More than disturb also and worsen more along with the area coverage of WRAN system.CPE can send at up use directional antenna, can avoid like this another sub-district descending caused interference.
Because the importance of the communication between the sub-district, in current IEEE 802.22 preliminary specifications, the method for two necessity is with solving from coexistence.Be respectively by from coexistence beacon message (CBP) with by the communication between the sub-district.
For mode by the communication between the sub-district, MAC is by allowing BS and client device (Consumer Premise Equipments, CPE) detect and the superframe control head accepting to come from collaborative base station (Superframe Control Header SCH) works in coordination with communication between the base station.For the base station, can intercept or dispatch each frame silence period that (quiet periods, descending and upstream QP) detect the SCH frame of other BS in its coverage by the cycle.
The shortcoming of this mode is: at first, it can only be used for to different Cell Broadcast CB SCH.In other words, this mode can not transmit SCH out of Memory in addition.In addition, when BS in broadcasting during SCH, the BSs of cooperation district and CPEs may not have the space to detect this SCH, this does not have in synchronous especially outstanding at different districts.And even the CPEs of cooperation district or BSs can detect broadcasting SCH, they may not know correct channel yet.Therefore, the reliability of the mode of the communication between this sub-district can not be guaranteed, and reliable communication link between the base station can not be provided.
In passing through the mode of CBP, 802.22 entity (just CPEs and BSs) can send the CBP bag, the CBP bag is used for setting up contact with the WRAN entity of other sub-districts, thinks that other sub-districts provide enough message pick-ups to obtain satisfied and the overlapping good coexistence in 802.22 sub-districts.In order to maximize the probability that the CBP bag is received by other 802.22 sub-districts of cooperating, CPE can not only be locked in its base station in the time of a frame.No matter when, CPE is scheduled and receives or when sending data to its (by US-MAP and DS-MAP message) BS, can only be locked on its base station.In the time of other of this frame, CPE must intercept and search for the CBP bag, and the CPEs that receives the CBP bag must wrap the BSs that offers it to these.
The shortcoming of this mode is: at first, if an entity (CPE or BS) of a sub-district 1 wraps to another sub-district 2 at transmission CBP, it can not guarantee that sub-district 2 exists an entity waiting this bag, and the CPEs of sub-district 2 and BS can not receive this CBP bag simultaneously when sending data.And even the CBP that the CPEs of sub-district 2 or BS can detected cells 1 bag, it can not determine this bag specifically transmits on which channel and which time slot; The a plurality of overlapped sub-district that may have in addition, different operators.Even the CPEs of sub-district 2 or BS know the working channel of all other overlay cells, can not predict sub-district 1 when in advance and send CBP and wrap CPEs or BS to sub-district 2, like this, may dispatch other sub-district outside the detected cells 1.Therefore, the reliability of this minizone communication mode by CBP can not be guaranteed, and communication link reliably can not be provided between the base station equally.
